ASML vs. NVIDIA: Which Technology Stock Is a Better Buy for 2027?

Can the company that builds the machines to make chips outpace the company that designs the chips themselves? Here is how to choose between ASML (NASDAQ:ASML) and Nvidia (NASDAQ:NVDA) for your portfolio.

ASML provides the critical lithography equipment used by every major chipmaker to etch tiny circuits onto silicon wafers. Nvidia is the leader in graphics processing units (GPUs) that have become the standard for training massive artificial intelligence models. These two giants are essential to the global tech ecosystem, making them top considerations for any investor.

The case for ASML

ASML sells lithography machines that use light to print circuit patterns on wafers. It has a near-monopoly on Extreme Ultraviolet (EUV) systems, which are necessary for the world's smallest and most powerful chips. These systems are incredibly complex, often requiring dozens of freight planes to transport a single machine and costing hundreds of millions of dollars each for high-end models.

In the 12 months ended Sept. 30, 2026, revenue reached nearly $43.6 billion, representing growth of roughly 22.5% compared to the prior year. During this same period, the company generated net income of approximately $14.9 billion. Growth was driven by strong demand in both the logic and memory markets as global chipmakers ramped up production for artificial intelligence applications.

As of its December 2025 balance sheet, the debt-to-equity ratio was roughly 0.2x, which compares total debt to the value of assets owned by stockholders. The current ratio was close to 1.3x, showing the company can cover its short-term bills with current assets. In the fiscal year ended Dec. 31, 2025, free cash flow reached nearly $12.3 billion, a key metric for semiconductor stocks.

The case for Nvidia

Nvidia provides GPUs and networking software that form the backbone of modern data centers. In its latest annual report, the company disclosed that two direct customers accounted for nearly 22% and 14% of total revenue. Customer concentration like this adds a layer of risk to the business, though its infrastructure is also used by major cloud providers and partners like Microsoft (NASDAQ:MSFT).

In the 12 months ended July 26, 2026, revenue reached nearly $303.0 billion, which was an increase of approximately 83.4% over the preceding year. Net income for this period was close to $192.9 billion. This massive revenue jump underscores how critical its chips have become for every sector trying to integrate generative AI and accelerated computing.

As of its January 2026 balance sheet, the company maintained a debt-to-equity ratio of approximately 0.1x, which compares total debt to shareholder equity. Its current ratio was roughly 3.9x, indicating it can easily cover its near-term obligations with assets expected to be converted to cash within a year. In the fiscal year ended Jan. 25, 2026, free cash flow reached nearly $96.7 billion.

Risk profile comparison

ASML faces risks from international trade policies that limit its ability to export top-tier equipment to certain markets. The business is also sensitive to its customers' investment cycles, which may delay large equipment purchases during economic downturns. Furthermore, any disruption in the complex supply chain required to build its massive machines could stall production.

Nvidia faces significant risks from evolving U.S. and international export controls, which have effectively prevented the company from competing in certain data center markets. Intense competition exists from established rivals like Advanced Micro Devices (NASDAQ:AMD) and large cloud service providers like Amazon (NASDAQ:AMZN) developing internal AI solutions. The company is also vulnerable to supply chain volatility and a high dependency on a limited number of foundries.

Valuation comparison

While both companies trade at identical price-to-sales multiples, Nvidia appears significantly cheaper on a forward earnings basis.

Which stock would I buy for 2027?

ASML is my pick for 2027 and a long holding period, because its risks are about timing, not about being displaced. A weak year for chip equipment orders hurts its results but doesn't threaten its place in the supply chain. ASML also gets paid regardless of which chip designer wins, since a challenger to Nvidia would still need its machines to make chips. A rival would have to replicate the machine and the years of engineering that went into it, and ASML has stayed ahead of that for a long time. I expect that to continue, though no business is completely safe.
Nvidia is a harder call right now. There are too many "unknown unknowns" after Jensen Huang's resignation and pending investigations for me to add to my position. I may need to take a few quarters or a year to see how things shake out. I'll be watching who the board names as permanent CEO, how the investigations and lawsuit resolve, and how the next few earnings reports read. I feel no urgency to run toward that fire right now.
